2. The TOPAZ Tracking Operation Pre Amplifier Zone circuitry solves ground loop noise problems common to automotive amplifier design This innovative new development allows vastly improved isolation of the input signal grounds from the power supply ground of the amplifier This is accomplished by allowing the source unit to control the potential environment of the entire input structure or zone of the amplifier This process improves the noise rejection of the amplifier by 30 40 dB an astounding 20 100 times better than amplifiers without TOPAZ THE RESULT Elimination of troublesome ground loop noise between source and amplifier J DSM Discrete Surface Mount Technology The DSM Discrete Surface Mount manufacturing process combines the advantages of both discrete components and integrated circuitry Rockford Fosgate is the only American amplifier manufacturer to haveinvested millions into this process DSM components differ from conventional discrete components in different ways They are more compact more rugged andihey efficiently dissipate generated heat Using them wherever appropriateallows theadvantages associated with discrete circuitry to be retained while also providing room for both highly advanced processing features and generous PC board copper paths where needed Their short lead out structures allow maximum audio performance and highest signal to noise ratios to be obtained in amplifies of desirable package size
